If you have done any type of home repair, you probably have at least a basic familiarity with the strange cylindrical tubes that dominate one aisle at every home improvement store.  This strange substance (with it’s even stranger delivery system) comes in a wide variety of types and colors with an even wider list of uses.

Caulk is one of those strange words that can function as both a noun and a verb.  You buy caulk at the store when you need to caulk something.  Makes sense right?  While caulk the noun refers to the putty like substance emitted from those strange narrow tubes, the verb refers to the action of sealing a gap using caulk.  With such a broad definition, you can imagine that the uses of caulk are limited only by your creativity.

The most basic uses of caulk involve sealing gaps within a building.  These gaps could be the gap between the wall and the edge of your shower or the gap between your window and the wall.  This sealing action is useful along the edges of counters to provide a watertight barrier or along molding to provide a smooth finish.  Caulk can also come in handy for patching up minor holes or dents, or as a seal on larger patch up jobs.

With hundreds of types of caulk in dozens of colors, it’s easy to find just the right caulk for the job; you just need to know which caulk is the right caulk for the job.

Acrylic latex caulk is used primarily as a sealant around windows and doors.  This type of caulk is easy to paint and offers easy application and cleanup.

Butyl rubber caulk is the strongest caulk available and is typically used for seals in concrete and brick.

Silicon caulk is a good all purpose caulk, providing an excellent seal on a wide variety of non-porous surfaces.
